Type "DT" Dovetail Pressure Locked Steel Grating

Type “DT” steel gratings have rectangular cross bars that are slotted to fit into pre-punched bearing bars which are assembled and permanently connected under intense hydraulic pressure. In addition to being one of the most aesthetically appealing floor gratings with its clean uniform lines, the interlocking design provides excellent lateral stability and axial load distribution. The multiple combinations of bearing bar / cross bar sizes and spacing on type “DT” gratings make them popular for architectural applications such as sun shades, fencing and infill panels with a deeper cross bar serving as a distinct architectural accent.

Type “DT” gratings are available in close mesh ADA conforming spacings. Type 7-DT-4 with 3/16″ thick bearing bars provides a net 1/4″ clear opening between the bearing bars. This narrow opening is often preferred in public areas where concerns of drainage and the presence of high heeled shoes converge.

Galvanized

IG GritWeld™

IG GritWeld™ utilizes processes developed for thermal sprayed hard surfacing and incorporates anti-skid ingredients to the super hard substrate. IG GritWeld™ offers the ultimate in traction and longevity for extreme environments. It is usually applied after galvanizing but can be applied prior to the coating process as well.

Fasteners

Saddle Clips

Tek Screws

Clima Seal or Stainless Steel Tek Screws are available to order upon request.

“G” Clips

Mechanical fasteners that are installed on the top surface of the grating and create a friction connection with the flange supporting the panel. “G” clips are easily installed without drilling or welding.

Weld Lugs

Plates punched with holes and shop welded between the bearing bars to facilitate bolting to the supporting structure. Bolts, screws or other connecting hardware shall be supplied by others.

Counter Bore Anchor Tabs

To be used with narrow spacing of close mesh gratings that require a solid fastener. Counter bore allows for the use of self-drilling fasteners which are recessed below the top surface.
